Late-night host Jimmy Fallon apologized on Twitter for his house band’s choice of intro music for Michele Bachmann this week, which liberals and conservatives alike condemned as offensive.

Fallon didn’t mention the name of the song — “Lyin’ Ass Bitch” — but he said he was sorry for what he called the “intro mess.”

“I'm honored that @michelebachmann was on our show yesterday and I'm so sorry about the intro mess. I really hope she comes back,” Fallon tweeted. “Actually it was a really fun interview. She helped me with my Minnesota accent. (I still sound Irish.)”

New York Rep. Nita Lowey, a Democrat from Westchester County, said Tuesday that Fallon, his band — The Roots — and NBC “should apologize” for the “sexist and offensive innuendo.”
